Use Seams around selections to Quickly create seams along face selections , combine existing UV islands and speed up your work when unwrapping organic and hard-surface models.
The add-on will clear existing seams from selected faces and add new ones around the selection.
Don’t clutter your UI with additional panels, just a simple button that gets the job done and can easily be assigned to a shortcut or added to the Quick Favorites menu.
This is my first commercially available script for blender so any feedback is greatly appreciated
